Figure 3. Mitochondrial DNA-based genetic analyses of philophthalmid species. (A) A maximum likelihood phylogenetic tree of the genus Philophthalmus. The tree was made using sequences of COI (693 nucleotide sites) under the substitution model HKYþG. The DNA accession number of each taxon is shown in parentheses. The tree was rooted by the outgroup taxon, Fasciola hepatica (M93388). The outgroup was removed from the tree to save space. Bootstrap percentages are indicated at branching points. A scale bar indicates the number of substitutions per nucleotide site. (B) A parsimony network of COI haplotypes (849 nucleotide sites) of Philophthalmus hechingeri n. sp. in a seashore of the Seto Inland Sea. The size of circles indicates the frequency of the haplotypes. Numerals within the circles mean the number of haplotypes. A closed circle indicates a haplotype, which is identical to that of Philophthalmus sp. from human in Aichi Prefecture (Sato et al., 2019). Tiny circles are hypothetical haplotypes.
